[0022] The present invention will be further described in detail below in conjunction with specific implementations and with reference to the accompanying drawings. It should be emphasized that the following description is merely exemplary and is not intended to limit the scope of the present invention and its application.

[0023] Non-limiting and non-exclusive embodiments will be described with reference to the following figures, wherein like reference numerals refer to like parts unless otherwise specifically stated.

[0024] like Figures 1 to 5 The disassembly tool for assisting the guide of the spindle of the machining center shown in the figure comprises a guide frame and a disassembly tool 1, wherein the disassembly tool 1 is movably mounted on the guide frame. The guide frame comprises a base plate 2, a guide plate 5, and a connecting column 3, wherein the two ends of the connecting column 3 are respectively connected to the base plate 2 and the guide plate 5, so that the guide frame as a whole is in a boss-shaped structure. The guide frame is provided with a guide hole, which passes through the guide plate 5 to the base plate 2, wherein the disassembly tool 1 is slidably arranged in the guide hole and can slide and displace along the axial direction of the guide hole. Specifically, the guide hole is composed of a first guide hole 2-1 arranged on the base plate 2 and a second guide hole 5-2 arranged on the guide plate 5. The two ends of the connecting column 3 are respectively connected to the periphery of the first guide hole 2-1 and the second guide hole 5-2. There are 2-4 positioning holes 2-2 around the base plate 2, and the positions of the positioning holes 2-2 correspond to the screw holes of the tool expansion cylinder seat of the machining center, so as to facilitate the connection bolts to fix the base plate 2. There are 4-8 connecting columns 3 to ensure the rigidity of the entire guide frame.

[0025] The disassembly tool 1 includes a guide rod 1-1 and a disassembly head 1-2. The disassembly head 1-2 is integrally formed and arranged at the lower end of the guide rod 1-1, and the upper end of the guide rod 1-1 is provided with an outer hexagonal head 1-4 or an inner hexagonal head for connecting a wrench. The lower end surface of the disassembly head 1-2 is provided with two bayonet pins 1-3 for disassembling the nut to be disassembled, and the guide rod 1-1 is movably arranged in the guide hole. The guide rod 1-1 can be displaced along the axial direction of the guide hole, and can also be rotated in the guide hole. When in use, the base plate 2 is first fixed by bolts through the screw holes of the expansion cylinder seat so that the position of the guide hole corresponds to the installation position of the nut to be disassembled; then the disassembly tool 1 is movably assembled in the guide hole, the disassembly head 1-2 extends toward the nut to be disassembled and the bayonet pin 1-3 abuts against the upper end surface of the nut to be disassembled; then the disassembly tool 1 is rotated so that the bayonet pin 1-3 is inserted into the connecting hole of the nut to be disassembled; finally, the hexagonal head 1-4 at the upper end of the guide rod 1-1 is rotated with a wrench to loosen the nut to be disassembled until the nut to be disassembled is removed.

[0026] In the above technical solution, the main body of the disassembly tool 1 is a straight rod structure, and the guide frame cannot clamp the disassembly tool 1 in the guide frame, resulting in the preservation of the entire tool unchanged, and the parts are easy to lose or the guide rod 1-1 and the guide frame cannot be quickly matched, which affects the work efficiency. Moreover, due to the large matching clearance between the guide rod 1-1 and the guide hole, the guiding effect of the guide hole on the straight rod type disassembly tool 1 is limited, and the guide rod 1-1 shakes slightly during the process of disassembling the nut. As an improvement, first, the disassembly tool 1 is designed from a straight rod shape to a stepped column structure, so that the diameter of the disassembly head 1-2 is larger than the diameter of the guide rod 1-1; then the size of the first guide hole 2-1 and the second guide hole 5-2 is changed accordingly, so that the diameter of the first guide hole 2-1 is larger than the diameter of the screw hole for assembling the nut to be disassembled, and the second guide hole 5-2 and the guide rod 1-1 are matched with clearance. In this way, the disassembly tool 1 with a stepped column structure can adapt well to the first guide hole 2-1 and the second guide hole 5-2. A cavity for accommodating the nut to be removed is formed between the first guide hole 2-1 and the second guide hole 5-2, and the height of the bottom plate 2 is less than the height of the nut to be removed. When the nut to be removed is completely removed, the upper part of the nut is in the cavity between the first guide hole 2-1 and the second guide hole 5-2. After the operator removes the bolts fixing the bottom plate 2, the tool can be removed to take out the removed nut. An axial inner screw hole is provided at the upper end of the guide rod 1-1, and a T-shaped end cover 1-5 is threadedly connected to the inner screw hole to limit the upper part of the guide rod 1-1, thereby limiting the guide rod 1-1 on the guide frame.

[0027] A further improvement of the above technical solution also includes a thrust bearing 7 and a stop pin 5-1. The thrust bearing 7 is fixed to the periphery of the first guide hole 2-1. The lower end of the connecting column 3 is welded and fixed to the upper thrust washer of the thrust bearing 7. The guide plate 5 is fixed to the upper end of the connecting column 3 by bolts, so that the guide plate 5 can be rotatably connected to the bottom plate 2 through the thrust bearing 7. The inner wall of the second guide hole 5-2 is provided with 1-2 stop pins 5-1, and the stop pins 5-1 are rotatably connected to the inner wall of the second guide hole 5-2 in the form of a shaft hole connection. In addition, a guide groove 1-6 is provided on the outer side of the guide rod 1-1 and is provided along the axial direction of the guide rod 1-1 to cooperate with the stop pin 5-1. In this way, when removing the nut, after the guide rod 1-1 is rotated with a wrench to loosen the nut to be removed, the operator can remove the nut to be removed by rotating the guide plate 5 by hand. The guide plate 5 drives the guide rod 1-1 to rotate through the stop pin 5-1, so that the nut to be removed is slowly removed. The anti-rotation pin 5-1 is rotatably connected to the inner wall of the second guide hole 5-2, reducing the friction resistance between the guide groove 1-6 and the anti-rotation pin 5-1 when the guide rod 1-1 spirals up. In actual operation, when a wrench is used to connect the upper end of the guide rod 1-1 to remove the nut, as the height of the nut rises, the distance between the wrench and the guide plate 5 gradually increases, so that the radial force on the guide plate 5 increases, and the friction between the guide rod 1-1 and the inner wall of the second guide hole 5-2 increases. This tool removes the nut to be removed by rotating the guide plate 5. During the disassembly process, the horizontal height of the guide plate 5 acting on the guide rod 1-1 remains unchanged, the disassembly process is stable, and it is convenient to rotate the guide rod 1-1.

[0028] A further improvement of the above technical solution also includes a spring 4 and a guide piece 6. The middle part of the guide piece 6 is provided with a third guide hole 6-2 which is in clearance with the guide rod 1-1. The side of the guide piece 6 is also provided with a plurality of bayonet holes 6-1 which respectively correspond to the connecting column 3, so that the guide piece 6 can be slidably arranged between the thrust bearing 7 and the guide plate 5 through these bayonet holes 6-1, and can move with the connecting column as the stroke. The upper end of the spring 4 abuts against the guide plate 5, and the lower end abuts against the guide piece 6. Under normal conditions, the spring 4 generates elastic force to squeeze the guide piece 6 against the upper thrust washer of the thrust bearing 7. In this way, the second guide hole 5-2 and the third guide hole 6-2 are used to guide the guide rod 1-1 at the same time, thereby improving the stability of the disassembly process. The first guide hole 2-1, the second guide hole 5-2, the third guide hole 6-2, and the thrust bearing 7 are coaxial.
